The share of the internet has grown significantly in terms of usage and level of influence. Among the internet media, OhmyNews is considered a alternative media representing Korea's independent internet news, and a typical example displaying characteristics of the internet news. The processing step can be divided as five stage, with recorded information and applicable technical element extractable from each stage. In this thesis paper, we have analyzed domestic and overseas metadata standard examples to devise metadata design plans. Items to be focused when redesigning metadata based on domestic and foreign case studies are as follows: First, user access should be convenient; second, connection with related information should be considered; third, accumulation of production, management, usage, storage, and action history should be considered; and fourth, the design should allow higher utilization of contents. In depth researches over internet media are already being carried out in external academic disciplines including the media information studies, information and communication studies, and communications studies. We expect that it will also be necessary to consider such researches over the internet media for mass media record management research going forward.

This research makes the metadata element design for Korean medicine research data management and re-use. Derived metadata elements are verified in research data of Korea Institute of Oriental Medicine. TTAK.K0-10.0976 Standard, DataCite metadata Schema and National Research Data Platform of KISTI were analyzed to derive the metadata elements. Including Identifier, 27 elements were derived as top-level elements with 29 mandatory elements, 13 recommended elements and 31 optional elements. The degree of elements' necessity and new metadata elements were investigated and suggested in the survey by six domain experts in korean medicine field. In this study subject classification for the korean medicine research data are suggested. The final version of metadata schema was tested and verified by comparing with the legacy metadata fields. The research results can be used to describe the Korean medicine research data: items and files.

It is not easy to access to the required data from the Web by using search engines because there are too many data selected and they do not provide enough information related to the corresponding data. Metadata is data about data. It includes information about data itself and contents of data as well. Users can acquire enough information about the corresponding data and access to the required data exactly using metadata, and therefore the data usability will be increased. In this paper, several metadata technologies and metadata models that are already in process of standardization or adopted as standards are analyzed, and the SeriCore Metadata Model for documents such as papers, project reports, technical reports, abstracts, and manuals, and graphic images that are in the field of science technologies on the Web is proposed. The SeriCore Metadata Management System that can generate, store, and retrieve metadata effectively is designed and implemented based on the SeriCore Metadata Model.

The purpose of this study is to design metadata for management and sharing of Yeogu data produced in the ecological field. Specifically, metadata is designed based on DCAT, which is designed to facilitate interoperability between data catalogs published on the web. In addition, ABCD, Darwin Core, and EML were analyzed and applied to metadata design to reflect the characteristics of the ecological field. As a result of the research, a total of 51 metadata elements were derived for managing research data in the ecological field, and 6 essential elements, 23 recommended elements, and 22 optional elements were included. The results of this study can be used to design a DB when building a research data management and sharing system based on metadata elements, and to suggest a metadata exchange format when linking with other systems.

As non-face-to-face elements became important due to COVID-19, the metaverse received social attention, and the MZ generation became the main users of public libraries. In light of this trend, it is necessary to introduce services for the MZ generation, the main users of public libraries, and to provide services tailored to social development. Therefore, this study investigated the perception of the metaverse through questionnaire surveys and semi-structured interviews, centered on the MZ generation, and then proposed a method for applying the metaverse to users in public libraries. According to the results of the study, the direction for the introduction of the metaverse in public libraries was suggested. First, it is necessary to provide basic education and information about the metaverse. Second, it is necessary to provide services that take advantage of the community based on communication. Third, a program that is not constrained by time and space should be provided. Fourth, services by librarians should be provided by enhancing the librarians' expertise on the metaverse. Fifth, services for generation M must be provided.

The purpose of this study was to designed the structure and elements of metadata that can manage and share research data produced in the food composition database. In order to derive metadata elements, mapping crosswalk was performed on 5 metadata such as DCAT, DataCite metadata schema 4.4, TTAK.KO-10.0976, AgMES, and FoodData Central. As a result of the study, the top 15 elements of the 'Resource information' metadata were derived, and 7 mendatory, 3 recommended and 5 optional elements, and the 'Composition analysis' metadata included 8 mendatory, 3 recommended and 1 optional element were derived to describe food composition research data, respectively. The derived metadata elements will be used as an item for systematic management of food composition data and can be used as basic data for sharing with domestic and international food composition databases.

There are marv problems in conventional database Construction of foreign scientific journal from material aquisition to DB loading. This paper's purpose is to design database construction model which utilizes available information resources scattered several locations and uses agents technology to gather essential metadata efficiently. This paper describes component informations of foreign scientific database and related available resources. And it describes a process of DB construction that include metadata gathering method, automatic metadata classification method, and metadata quality monitoring method.

본 논문에서는 멀티 에이전트 모델에서의 정보 검색 서비스 지원에 있어 이동 에이전트의 이주 호스트(이하 노드) 자동 탐색, 이주 순위 결정 및 검색 적중률 분석을 통한 보다 정확한 정보 서비스 지원을 위해 메타 데이터를 이용한 네이밍 에이전트를 설계한다. 기존의 이동 에이전트 시스템에서는 이동 에이전트가 이주할 노드의 IP와 포트번호 또는 CORBA 구현 저장소에 등록된 구현 객체의 이름 등을 사용자가 직접 지정해주어야 함으로써, 이주 대상 노드에 대한 구현 객체 연결을 위해 물리적인 정보들을 반드시 알고 있어야 하는 단점이 있다. 따라서, 본 논문에서는 각 네이밍 서비스별로 구현 객체 관련 정보들을 메타 데이터 테이블에 저장 및 관리하고, 사용자 입력 검색 키워드에 대한 해당 구현 객체의 객체 참조자를 반환하는 네이밍 에이전트를 설계한다. 설계된 네이밍 에이전트는 메타 데이터를 이용하여 정확한 정보 검색을 수행하기 위한 노드 이주를 지원하고, 이를 통해 다양한 사용자의 요구에 따른 정보 검색 정확도의 향상은 물론 이동 에이전트의 순회 검색 수행 시간의 단축 및 한정된 네트웍 환경에서의 트래픽 감소를 유도한다.

최근 네트웍의 보급과 지리정보의 활용이 증가하면서 효과적인 지리정보의 교환과 접근에 대한 중요성이 강조되고 있다. 하지만 기존의 GIS 데이터는 지리적으로 분리된 여러 부서나 조직에서 생성되고 있으며, 공간 정보 유통을 위한 클리어링하우스 등이 서로 다른 DBMS 상에서 독자적인 스키마를 가지고 개발되어 있다. 이러한 이질적인 구조와 구현 환경으로 인해 일반 사용자들이 서로 다른 GIS 데이터베이스를 접근하여 검색하는데 많은 어려움이 따르고 있다. 본 연구에서는 OMG의 메타데이터 교환 표준인 XMI로 표현된 이질적인 GIS 데이터베이스의 메타데이터를 통하여 사용자에게 각 데이터베이스의 구현 환경과 스키마에 독립적인 공간 데이터를 검색 기능을 제공하는 검색시스템을 구현하였다.

The Internet has gained popularity because it provides various information in digital format. However, it is very difficult to provide methods which make it possible to search adequate information resource from bulk of Internet information. In this paper, we define a SGML metadata DTD, named SeriCore, and design and implement a metadata retrieval and management system which can store, retrieve and manage the Internet metadata efficiently.
